A SPECIFICATION forming* part f Letters Patent N0. 680,599, dated August13, 1901.

Application ledAngust 8, 1900. Serial No. 26,813. (No model.)

T0 all whom/'zit may oon/cern:

Be it known that We, HARVEY P. JONES and HARRY S. JONES, citizens oftheUnited States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful Improvement in Punches, ofwhich the following is a specification.

Ourinvention relates particularly to handoperated punches, and ourprimary object is 1o to provide a portable machine of this characterwhich is both light and strong.

Our improved machine is particularly adapted for use in punching thebinding-perforations for ledger-leaves of the loose-leaf type, and itmay be remarked that the machine Was designed, primarily, to meet thedemand for a suitable punch Which could be taken from office to officeand used in perforating leaves Where perforation or reperzo forationmight be required, as by a change in system.

` In the accompanying drawings, Figure l is a plan view of a machineembodying our improvements; Fig. 2, avertical section through a combinedguide and female die, the section being taken as indicated in Fig. 3;Fig. 3, a horizontal section of the same, taken as indicated in Fig. 2;Fig. 4, a view of the detached male die; Fig. 5, a section of the sameat line 3o 5 of Fig. 4; Fig. 6, a section at line 6 of Fig.

l; Fig. 7, a view of the machine in front elevation; and Fig. S, an endview of the eccentric-shaft employed.

A represents a platform comprising hinged sections A and A2; B, a guideor gage movably secured thereon by bolts a' passing Y through saidsections and through slots d on the gage and equipped with Winged nutsa2; C, a cast-metal die support or bed; D, an ad- 4o justably-supportedcombined die and guide blocks; D and D2, integral and removableretaining-strips, respectively,for securing the blocks D to the base C;E, upright guides rising from the base C; F,a cross-head moving on saidguides; F', an eccentric-shaft journaled in the upper ends of saidguides; F2, an operating-handle for said shaft; F2, links journaled oneccentrics b and supporting the cross-head, and F4 adjustable male diesor 5o punches carried by said cross-head.

The platform-section A comprises a board c and cross-pieces or ribs c'on the lower surface thereof. The section A2 comprises a narrowed boardc2 and cross-pieces c3. The abutting ends of each set of cross-pieces cc3 55 are connected by a hinge c4. The pieces c3 project beyond thefront edge of the board c2 and are recessed to receive and support thepart C. The part C is in turn recessed at its rear upper corner toreceive the front edge of '6o the board c2. The top surface of theplatform is thus made flush with the top surface of the strip orshoulder D'. The base C is provided With a longitudinal slot d2, throughwhich the cuttings from the dies drop.

The combined guide and die blocks D are provided with inclined surfacesd d', which are engaged by overhanging inclined surfaces Of theretaining-strips D and D2. Each block has an upper guide portionfandaloWer 7o die portion f', separated from the upper portion by ahorizontal leaf-receiving slot f2 in the front portion of the block. Avertical guide-perforation f3 and die-perforation f4 intersect the slotf2, and these perforations are in turn int-ersected by a vertical slotf5, extending from the rear of the block. A hardened-steel facing orshearing plate f6 is detachably secured to the upper surface proper ofthe die portion of the block by screws f7. So

Each male die comprises a cylindrical stem g, a retaining-flange g', areduced cutting end g2, and a separately-formed Wing g3, socketed in avertical slot, as shown. The Wing g2 moves in the slot f5 and serves tocut a slot 85 leading from the edge of the paper to the perforation.

Fig. 6 shows the cross-head F provided with a longitudinally-disposeddie-retainer h, having a horizontal flange 7L', between which go and thelower surface of the cross-head fit the anges g' of the adjustable maledies. In operation the male dies never leave their guides, so that thereis no opportunity for binding, with consequent danger of breakage. 9 5

It will be readily understood that the dieblocks With the male dies inplace in their guides can be disposed as desired along theretaining-strips D' D2, after which they are firmly clamped in place bythe member D2. loo The leaf to be punched is placed With its top orbottom edge along the gage B and its binding-margin extending throughthe slotf2. The location of the binding-perforations can of course beregulated by adjustment of the dies.

The machine is commonly taken from office to ofiice in a casing or chestprovided with suitable handles. The portability is greatly facilitatedby making the platform capable of folding. When desired, certain of thebolts securing the gage B may be removed, and the gage can then be swungto the position indicated by dotted lines in Fig. 1. This permits thesection A' to be swung beneath the section A2. Blocks 7c, correspondingto the hinge thickness, serve to prevent injury to the hinges when theparts are folded. The cross-head is shown depressed in the drawings. Bymoving the handle F2 to a vertical position it is evident that thecross-head will be raised. The ends of the slots f2 act as stops orgages for the binding edge of the leaf, as is evident.

The blocks D may be of cast-iron, excepting the shearing-plates f6.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a portable punching-machine, the combination of a platformcomprising downwardly-swinging hinged sections, a female die connectedwith one of said sections, a reciprocating male die coacting therewith,and a movable guide or gage secured to the upper surface of saidplatform and extending across the junction of said sections,substantially as and for the purpose set forth.

2. In a punching-machine having a suitable base provided with inclinedretainingshoulders and having also a plurality of adj ustably-supportedreciprocating male dies and a suitable platform, a plurality ofadjustably supported separate integrally formed combined guide andfemale die receiving said male die and provided with upwardly-convergentsurfaces engaged by said retainingshoulders, each combined guide and diebeing provided with a horizontal recess, the lower wall of which isflush with the upper surface of said platform, substantially as and forthe purpose set forth.

3. In a punching-1nachine,the combination of a Wooden platformcomprising two downwardly-swinging sections, one of said sections beingcut away at its upper front portion, a metallic die-block base supportedon the recessed portion of the front section and having the surface ushwith the top surface of the platform and provided also withupwardly-convergent retaining-shoulders, an integrally-formed combinedguide and female die adjustably supported by said base and provided withupwardly-convergent surfaces engaged by said retaining-shoulders andhaving a horizontal slot in its rear portion, the lower wall whereof isiiush With the adjacent surface of said base, and a reciprocating maledie supported from said base and received by said combined guide anddie, substantially as and for the purpose set forth.
